Microbead silica
Application areas:
Environmentally friendly silica,one is dedicated to rubber products,fluidity,good dispersion,and no dust.Future trends replace powdered silica.The second is used as a carrier for veterinary drugs,pesticides,and medicines to increase their flow properties.Such as acidifiers in the feed and antibiotics for veterinary drugs.
